We're dividing 67824449 by 450 
The aim is to understand the frequency of 450 in 67824449.

Moving on to step 1:
If we divide 6 by 450, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 450

Let's proceed to step 2:
If we divide 67 by 450, we get 0 and a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Take the next digit (8) from the dividend and append it to 67, then repeat: 678 / 450

Let's proceed to step 3:
678 divided by 450 is 1 with a remainder of 228.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 450 from 678, we get 228.
Bring next digit (2) of the dividend behind the 228 and repeat the process: 2282 / 450

Advancing to step 4:
450 goes into 2282 5 times with a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 2250 from 2282 leaves us with 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 450

Moving on to step 5:
If we divide 324 by 450, we get 0 and a remainder of 324.
Put 0 as the next digit of the answer. 
Result so far: 150.0
Deduct 0 from 324 and we're left with 324.
Append the next digit (4) from the dividend to 324 and continue with: 3244 / 450

Moving on to step 6:
450 can be fit into 3244 7 times, resulting in a remainder of 94.
Put 7 as the next digit of the answer. 
Result so far: 1507.0
Deduct 3150 from 3244 and we're left with 94.
Append the next digit (4) from the dividend to 94 and continue with: 944 / 450

On to step 7:
450 goes into 944 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 15072.0
Subtracting 900 from 944 leaves us with 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 450

Let's proceed to step 8:
450 goes into 449 0 times with a remainder of 449.
Record the quotient 0 as the next digit in the result. 
Result so far: 150720.0
Subtract 0 from 449 to get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Let's proceed to step 9:
If we divide 4490 by 450, we get 9 and a remainder of 440.
The number 9 becomes the next digit in our result. 
Result so far: 150720.9
Subtract 4050 from 4490 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 10:
When dividing 4400 by 450, we get 9 with a remainder of 350.
Use 9 as the next digit of our solution. 
Result so far: 150720.99
Subtracting 4050 from 4400 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

After the division, we end up with 150720.99 and a remainder of 0.35.
